I have two Eclipse installations and for each of them a desktop file, see below.
For the icons, I'm using eclipse in both cases with an activated Numix Icon Theme.
If I search and start the applications via Activities, the icons are correct.
But not in the taskbar on the left hand side after the start
How can I change this behaviour, I want the Numix icons on the left hand side also.
Some more details
find /usr/share/icons/Numix-Circle -iname "*eclipse*"
